Homeland Security Secretary Janet Napolitano was in San Diego on Monday as part of a two-day tour to inspect border security along the U.S.-Mexico border and rally for immigration reform. Napolitano said the border is about as secure as it’s going to get.

“I believe the border is secure. I believe it is a safe border.”

Napolitano cited federal figures showing apprehensions of illegal border crossers are down 50 percent since 2008. Meanwhile, confiscations of bulk cash, illegal drugs and weapons along the Southwest border shot up over the last three years.

The visit came a week after a bipartisan group of U.S. Senators outlined a proposal for overhauling the nation's immigration system. The proposal calls for securing the border first.

Napolitano said the border could never be 100 percent secure and her administration would continue to put every resource possible into border security.

“But we need immigration reform to go along with this,” Napolitano said.

She said enforcing the nation’s immigration laws was "intrinsically and inextricably related to a legal immigration system," and the current system is broken.

Napolitano expressed support for the so-called "Gang of Eight" U.S. senators working to craft an immigration overhaul bill.
